What is this long tailed shark doing?

I saw it desperately swinging its tail above the umbrella cover of an Arctic Xia jellyfish, twisting its slender body, and then creating a water flow, impacting the umbrella cover of Xia jellyfish and driving it to move slowly.

Xia jellyfish itself has the ability to move. It changes the volume of the inner cavity by shrinking the shell and squeezing the inner cavity, ejects the water in the cavity, and moves by spraying water. This is a little similar to the gun squid, which moves by the reaction force ejected by the water flow.

This is a way for them to swim along the horizontal plane. If they want to sink and float up and down, they rely on a special gland in the body, which can emit carbon monoxide, expand and absorb water, and then float up.

When they want to sink, they will release carbon monoxide. If they want to float up, they will release carbon dioxide again into the airbag and float again.

Generally speaking, when they choose an environment, they will not move again, but open their tentacles to wait for the food to come to the door, until they encounter enemies or a big storm, they will sink to the bottom of the sea. Or, if there is no food in the sea, they will move.

However, the Arctic Chardonnay jellyfish is too large and difficult to move, so it is not good at swimming. It often moves with the help of wind, waves and water.

Now there is no big wind and waves, no strong undercurrent, and there is plenty of food around. These Arctic Xia jellyfish naturally have no power to move.

This long tailed shark is trying to create this kind of power. It rotates its long tail like an oar to form a fairly powerful water flow in a small range, driving the Arctic Xia jellyfish to move in the direction it guides.

The movement of organisms has inertia, and the lower the biological inertia, the greater.

Arctic Chardonnay jellyfish have no brain and intelligence. They are very low-level creatures, so when they feel the water flow driven by long tailed sharks, they will automatically follow them after drifting for a while.

This Arctic Chardonnay jellyfish is like this. At this time, it has entered the state of autonomous swimming.

Under the control of muscle fibers extending from the top of the epidermis to the end of the umbrella, its lumen shrinks and expands continuously. When the inner cavity expands, the water will be slowly sucked in; Then the inner cavity shrinks rapidly, extrudes the water out of the cavity, and the thrust generated by the water jet will make it move.

However, its body is too large, the driving force is relatively small, and its moving speed is very slow.

The long tailed shark waited patiently and tried his best to help the Arctic Xia jellyfish move. Qin Shiou didn't know what it wanted to do, so he looked strangely nearby.

This long tailed shark shocked him a lot. This guy seems to have a high IQ. For example, last time it designed to let the giant demon fight with the black cover giant bug. If Qin Shiou didn't help, it is estimated that the giant demon would be killed now.

In other words, the giant squid in the sea was almost killed by a long tailed shark, which is so legendary!

It took more than an hour. After moving four or five kilometers, the long tailed shark left, and then its moving speed slowed down. Because it can't feel the water flow, it won't swim blindly.

After the long tailed shark left, Qin Shiou also wanted to leave. He thought the long tailed shark was just playing, but when the sea god realized that he had left a distance, he suddenly noticed something strange.

This Arctic Chardonnay jellyfish has a unique location. It is in a Chardonnay jellyfish group, and there are seven or eight Chardonnay jellyfish up, down, left and right. After these large jellyfish stay in the water, they cover a sea area.

Qin Shiou stared, and an idea slowly emerged: this rosy jellyfish group seems to be a trap.

Who is the longtail shark going to deal with when it makes this trap? Subconsciously, Qin Shiou thought of the giant demon.

Sure enough, about ten minutes later, the long tailed shark suddenly jumped back. Not far behind it, a scarlet super monster was chasing angrily, and the giant demon appeared!

The big tail of the long tailed shark shakes fast. It looks like a sharp arrow. It rushes to the Arctic Xia jellyfish with lightning speed, and then plunges into it!

There are large gaps between the Arctic Chardonnay jellyfish. This trap is not reliable. The long tailed shark uses these gaps. It shuttles through the Chardonnay jellyfish group without any damage.

It's really walking among thousands of flowers, and leaves don't touch your body! Qin Shiou can only say that I have taken Qin Ritian!

The giant demon chased behind angrily. Its tentacles carried a heavy mace, so although it was not slow, it still couldn't catch up with the long tailed shark.

In particular, this long tailed shark is particularly cunning. As soon as the giant demon gets closer, it turns, and the turning happens to be the biggest dead corner in the movement of the giant demon.

After rushing into the rosy jellyfish group, the giant demon instinctively felt dangerous and wanted to stop.

But all marine creatures have mobile inertia. The giant demon is too large, especially with great inertia. It was late when it wanted to stop, and finally got into the Xia jellyfish.

There is a gap between the Chardonnay jellyfish. This gap is relative. For the long tailed shark, it is a gap. For the huge monster, it is nothing.

The two sides fought hand to hand, and the Daxia jellyfish immediately shook all its tentacles to attack the giant demon.

The giant demon is heroic. Fight and fight. I'm afraid you can't be a bird?

One word, don't advise, just do it!

The two longest tentacles of the giant demon stretched out, stirred the tentacles of the Arctic Xia jellyfish and tore them up. In addition, its steel mace also attacked the situation, chiseled on the umbrella cover of the Xia jellyfish and directly tore a big hole for it.

Jellyfish have strong vitality without losing water. They have no brain, no heart and almost no cover door. If any creature wants to kill them, they can only swallow them whole, just like leatherback turtles.

But such means can only deal with small jellyfish, such as the Arctic Xia jellyfish with tentacles tens of meters. Even if the real North Sea giant demon comes, it can't swallow it in one bite.

If you can't swallow them, you have to fight them.

Qin Shiou has understood the plan of the long tailed shark. This guy is too smart, or his belly is too black. He even designed such a trap to deal with the giant demon!

This time it is still watching the tiger fight on the mountain. The giant demon is led to fight with the Arctic Xia jellyfish. A Arctic Xia jellyfish may not be the opponent of the giant demon, because the poison resistance of the giant demon is very strong.

However, there are seven or eight Arctic jellyfish around here

The fighting style of the giant demon is thunderbolt means and thunder storm. After it was entangled by the first Arctic Xia jellyfish, it began to float around with it. In this way, it met the second Xia jellyfish and was naturally entangled again

The giant demon continues to roll and turn around, and will continue to entangle other Arctic Xia jellyfish. In this way, more and more entanglement, quantitative change causes qualitative change, and its situation becomes more and more dangerous.

The long tailed shark wanders in the distance, calmly watching this scene, like a killer, looking for his opponent's weakness, and then closing his throat with a sword!
